WINDSHIELD CLEANER.

Original No. 1,420,538, dated June 20, 1922, Serial No. 460,784, fled Kay 16, 1921. Application for reissue filed April 80, 1923. Serial No. 685,713.

To all whom it may concern:

Be it known that we, FRED G. FOLBERTH and WILLIAM M. FOLBERTH, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Windshield Cleaners, of which the following is a specification.

This invention relates to windshield cleaners, and is an improvement over the construction shown in our co ending application Serial No. 468,485, fi ed May 11, 1921. I

In the said copending application, we

1 have disclosed and claimed a windshield cleaner comprising ,a cylinder, pistons -arranged in the cylinder, an actuating member oscillated by the reciprocation of the pistons, and a pair of cleaner elements spaced from each other and operated by the oscillation of the actuating members In thepresent invention, there is royided a cylinder having. a pair of s ace pistons arranged therein, .a main sha t, means for Id transmitting motion from thepistons to the main shaft, to oscillate said shaft, a pair of spaced cleaner shafts, means for driving one of said cleaner shafts from the main shaft, and connecting means between the two shafts so to operate the shafts in unison.

An important object of the present invention is to provide a pair of cleaner elements mounted on cleaner shafts which extend transversely of the cylinder intermediate the 36 ends of the cylinder.

A further object is the rovision of a windshield cleaner comprising a cylinder adapted to be built in to the windshield In the accompanying drawings, we have shown one embodiment of the invention. In this showing:

Fi re 1 1s a front elevation of the windshielg of a motor vehicle showing the invention applied,

- Figure 2 is a transverse vertical sectional view on line 2-2 of Figure 1,

Figure 3 is a horizontal sectional view through the windshield cleaner,

so Fi ure 4 is a longitudinal vertical sectional view, and, c

Figure 5 is a similar view on an enlarged scale. V

. Referring to the drawings, the reference of a web 10, of arcuatecross-section,

' valve mechanism. While numeral 1 designates the windshield of a motor vehicle made of suitable transparent material, such as glass. The windshield is provided with a frame 2, referably formed of metal, and made tubu ar. Any suitable means may be provided for securing the windshield to t e frame. As shown, an arouate plate 3 is secured to the frame, the plate being provided with spaced flan s 4, adapted to be arranged on o posite si es of the windshield. The upper liorizontal portion of the frame is provided with-a. pair of cylindrical plates 5, arranged therein and spaced fromeach other to form a cylinder A pair of pistons 7 are arranged within the cylinder, the pistons being pro vided with suitable leakage. As shown, retained in place b pistons are connecte the packing may be to each other by means referably arrangedadjacent the bottom 0 the cylinder. As shown, the web is provided with a longitudinal passage 11 for the reception'of a valve ac'tuatin member 12. As the particular-valve mec anism employed forms no part of'the present invention, a detail description thereof is deemed unnecessary.

The pistons are adapted to be reciprocated m the cylinder by means of pressure or suction, the opposite ends of the cylinder bein alternately placed in communication wit a source of pressure or suction by suitable any type of operating mechanism may be employed, we prefer to connect the cylinder to the intake manifold of the engine to operate the .pistons by the suction in the intake manifold, as disclosed in the co ending a lication of William M. Folbert Serial 0. 273,143, filed January 29, 1919, now Patent No. 1,405,773. As shown, a ipe 13 is connected to an enlar ment 14, ormed on one end of the cylin er, the pi e 13 being connected to the intake manifol of the engine (not shown) and communicating with a chamber within the enlargement 14.

A-main shaft 15 is arranged transversely of the cylinder, intermediate its ends, the shaft being mounted in suitable bearings 16, formed by enlargements in the cylinder wall. This shaft is rovided with a drum 17, suitably secured packing 8 to prevent an'end plate 9. The

thereto to revolve therewith. The main shaft is oscillated by the reci rocation of the me mm of a flexible e 10, as at 20.

A pair of cleaner shafts 21 are also ar-, ran transversely of the cylinder interm late its-ends and spaced from each other. One of these shafts is provided with a gear wheel 22, meshing with a pinion 23, ar-

sha are further provided with sprocket wheels 24 over which passes a sprocket chain 25, connecting the two shafts to eachother. A cleaner rod 26 is secured to each of "the cleaner shafts and a cleaner element 27 is mounted on each of thecleaner rods.

Referring to Figure 1 of the drawings, it

- will be seen that when the cylinder is connected to a source of pressure or suction to alternately create re or suction in the opposite ends of e cylinder and thus reci rocate the pistons, the cleaner elements 27 will oscillate over the windshield in an arc of a circle'and remove rain, snow,;.or-other material therefrom. The reciprocationof the pistons oscillates the main shaft 15 by means of a flexible element 18, passing over the drum 17, One of the cleaner shafts is driven from the main shaftby means of gear 22 and pinion23, and the oscillating movement is transmitted to the other cleaner shaft by means of sprocket wheels 24 and chain 25. U

The construction of a windshield cleaner wherein the cylinder is arranged withinthe windshield frame is advanta us, in that it eliminates the necessit o mounting a cylinder on the windshiel frame.

It is to be understood thatthe form of our invention herewith shown and described is to betaken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts ma be resorted to without departing from t e spirit of the invention or the scope of the subjoined claims.

Having thus described our invention, we claim:

1. A windshield cleaner comprising a cylinder, a pair of reciprocating pistons mounted therein, means for reciprocating said p'istons, a main shaft, connecting means between said shaft and said pistons to actuate said shaft when the istons are reciprocated, a pair of cleaner afts, means for actuating said shafts in unison, and means for connecting one of said shafts to the main shaft.

2. A windshield cleaner comprising a cylinder, a piston mounted ,in said cylinder, means for establishing differential pressures in said cylinder to reciprocate said piston a main shaft arranged transversely of said frame, of a motor'casing forming a part of II mp1s piston is reciprocated, a pair of cleaner' shafts, drive means connecting one of said shafts to the main shaft, and means for connecting said shafts to each other.

3. A windshield cleaner comprising a cylinder, a pair of reciprocating pistons mounted therein and spaced from each other, a web connecting said pistons, means for reciproeating and pistons, a main shaft arranged intermediate the end of the cylinder, a flexion the main shaft. The cleanerkble element having its ends connected to one of said pistons and to said web, the intermediate Hortion of said flexible element being coile aroimd said main shaft to oscil late it when the istons are reciprocated, a

ing 1 means between said-pistons and said main shaft, a ing transve y of said cylinder and spaced from-each other a gear mounted on one of said cleaner sha a inion mounted on the Y main shaft and meshin with said gear to drive said cleaner sha, and drive means connecting the other cleaner shaft to the first mentioned cleaner shaft. 5. A windshield cleaner comprising 9. cylinder, a pair of spaced pistons mounted therein, means for reciprocatin said pistons, a'main shaft mounted in arings in said cylinder, drive means connecting said shaft to said istons, a pair of cleaner shafts mounted in rings in said cylinder, and spaced from each other, means for connecting one of said cleaner shafts to the main shaft, sprockets arranged on said cleaner shafts in alinement with each other, and a a remainder to form a motor casing, an actuiae atin=g member mounted in said casing, a

cleaner shaft, and connections between said actuating member and said cleaner shaft.

8. The combination with a windshield transversely of 'said cylinder intermediate its ends, connect-- air of cleaner shafts extendsaid frame, an actuatin member arran therein a cleaner shait, and connect means tween said actuating member an said cleaner shaft.
